Description

Material fork supporting rod of heat treatment furnace Technical Field The utility model belongs to the field of heat treatment furnace production equipment, and particularly relates to a heat treatment furnace fork supporting rod. Background The heat treatment furnace fork supporting rod is mainly applied to automatic feeding and discharging of a sheet metal part heat treatment furnace, the existing heat treatment furnace is required to be subjected to high-temperature and other processes in the production process, feeding and discharging are required to be carried out through the heat treatment furnace fork in the production process, most of the heat treatment furnace fork supporting rod is made of steel pipes, the steel pipes are affected by temperature in the high-temperature use process, the structure of the steel pipes is easy to deform, the contact surface between the existing supporting rod and a product is large in the use process, the temperature change of the product is easy to be too fast, more oxidation layers are generated, and the continuous use of the supporting rod is not facilitated. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide a material fork supporting rod of a heat treatment furnace, so as to solve the problem of easy deformation in the use process of the existing supporting rod. In order to achieve the purpose, the material fork supporting rod of the heat treatment furnace comprises a supporting tube, wherein a first reinforcing tube and a second reinforcing tube are respectively arranged on two sides of one end of the supporting tube, the supporting tube is of a hollow structure, an inner reinforcing tube is arranged inside the supporting tube in a fitting mode, a blocking plate is arranged on one end, opposite to the first reinforcing tube, of the supporting tube, an air pipe joint mounting plate is arranged on one end, opposite to the blocking plate, of the supporting tube, an air inlet is formed in the air pipe joint mounting plate in a communicating mode with the supporting tube, and air is blown into the inner cavity and the outer cavity is exhausted through the fact that the supporting tube is provided with a double-layer cavity, so that the purpose of reducing temperature is achieved. The preferable structure of the scheme comprises that an air inlet cavity is arranged inside one end of the supporting tube opposite to the air inlet. The preferable structure of the scheme further comprises that exhaust cavities are circumferentially distributed on the inner side surface of the support tube, the exhaust cavities are arranged between the inner reinforcing tube and the support tube, and the exhaust cavities exhaust gas from the tail end of the exhaust cavities to take heat away. As another preferable structure of the present solution, the support tube at the bottom of the first reinforcing tube is provided with notches, and the notches are circumferentially distributed on the support tube. As another preferable structure of the scheme, the exhaust cavity supporting block is arranged in the inner layer reinforcing pipe. The utility model has the beneficial effects that the purpose of reducing the temperature is achieved by arranging the support rod into a double-layer cavity, blowing air into an inner-layer cavity and exhausting air from an outer-layer cavity, and specific embodiments are further described in the following examples. Drawings FIG. 1 is a schematic diagram of the overall structure of the present utility model; FIG. 2 is a sectional view of the B-B position; FIG. 3 is a sectional view of the A-A position; In the figure, a first reinforcing pipe, a second reinforcing pipe, a 3 supporting pipe, a 4-exhaust cavity supporting block, a 5-inner reinforcing pipe, a 6-blocking plate, a 7-tracheal joint mounting plate, an 8-notch, a C air inlet, a D air inlet cavity and an E air exhaust cavity are arranged; Detailed Description The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
